    Abstract：
    Accurate calculation of dynamic reserves is important for gas field development. The traditional pressure drop method only based on the pressure test data has fewer reference points which can cause the calculation results inaccurate. In this paper, the well production data is applied to draw the pressure drop curve. Pressure tracking curve can be used to solve the inaccuracy of the traditional method. In order to eliminate the well interference effect, entire well group is taken as one well to calculate the dynamic reserves by integral pressure-drop method . The conclusion has been approved by the dynamic reserves calculation results of two wells in Shan2 reservoirs, which verifies the validity and reliability of the method.
